Passing argument


When the command is started via a shell script (manual or automatic), the arguments:

  • are separated by one or more blank space
  • should be quoted if the value has space or reserved character in it

For more information on how to pass argument, you should read the documentation of your shell:

Because the number of argument may become quite large, application uses generally configuration file to pass them.

You pass the location of the file as argument, the application parses it and read the argument in the file.


A command may start a background (daemon) process. In this case, the service system will execute the command and its arguments.
